Oh, Sorry to see that. Looked like a classic gull stall flat spin. Can you show us the break?

No need to show me the break, I saw it as I single framed through the video.

I think that the crash is 100% my fault. The CG was mostly correct, as the model could fly straight without much elevator correction .
I feel like there was too much gain in the aileron to rudder mix , as can be seen in the companion model file that I posted earlier.
I will contact the Aloft team about the details for ordering the three replacement outer panels for the right wing.

Just let me know what parts needed I'll replace for free (just pay the shipping )
 
I singled framed through the video and didn’t see where you made a mistake. Your inputs looked correct with the rudder but the bird looked to be in a stall and not responding. I could plainly see the rudder trying to bring the nose to the left but in the stall she just kept spinning to the right. After the rebuild try just moving the CG forward about 3mm to 4mm, your close but IMHO just a bit tail heavy.

I saw a zoom from launch with a dive (correction) followed by a pull up into a stall. The right wing looked stalled. This was aggravated by the lower right aileron (didn't see the aileron positions, but assume this based on the rudder mix mentioned).

I think the model was tail heavy resulting in the zoom up and subsequent reaching the critical angle of attack on the pull out from the dive. I think moving the CG forward a few mm would solve the issue. I don't think this was a mix or mix value problem.
 
A million ( 10^6 ) thanks to Rafael , who gave me spare wings for my seagull.
Same also to Jarron, who gave me a tour of the Aloft Headquarters .
And , of course many thanks to Wayne , the prime mover and inspiration behind this wonderful organization .

thanks again , from Jure Z.
 
Is this a reference to the Opera?

I know we are all excited to see this fly and fly right. So take your time.
 
YOWZER!!!
Even the professionals wanted in on the act.

So what did you do with the trim set up the second time around?
 
Expo!!

You will want some elevator for inverted work.

Back to one of my earlier concerns. What are the servo arm lengths? I'm thinking that you could move the push rods one hole closer to the servo axis. This will cut down on the throw and slow down the response. While upping the power and resolution of the servo by moving the outputs closer to 100-120%.
